| 中文摘要 |
| 介绍了系列采样装置,包括沉积物-水界面取样器,孔隙水隔气抽取装置和电渗析沉积物剖面切割工作台等.可对75m深水湖泊采集到30-90cm的沉积物术及10-30cm底层水样品,并可在野外现场分样和提取孔隙水.沉积物分样的厚度最小是0.1cm.整套装置重量轻、可拆卸、操作简便且便于野外运输. |
| 英文摘要 |
| In order to investigate the lacustrine environment, and treat the environmental problem, it is necessary to get undisturbed samples. A whole set of devices for collecting undisturbed samples near the sediments-water interface was developed. This includes a sediment sampler, a sedimentary pore water sampler, and a electro-osmotic guillotine system for core-cutting, and so on. These devices can be used for sampling in lakes as deep as 75 meters, collecting columns of sediment sample of 30-90cm high, and columns of upling water of 10-30 cm high. The minimun seperation thickness of the sediment sample is 0.1 cm. The set of the devices is rather light, easily disassmbled, convenient to transport, and easy to operate. |
